WILLIAM A. HEIDE, OF DETROIT, MICHIGAN.

. GARBURETER CONTROL-VALVE.

Application filed December 28, 1918.

To all whom may concern: 4

Be it known that I, WILLIAM A. Huron, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and use ful Carbureter Control-Valve, of which the following is a specification.

The subject of this invention is a carbureter control valve, which while intended primarily for use with carbureters, is capable of use wherever such valves may be neediul.

The main object of the invention is the provision of means for controlling the passage of air through the intake or mixing chamber, such means being susceptible of wide variation to meet the various require ments and conditions of a motor.

Another object of the invention is the provision of means for operating the valve.

Another object of the invention is the provision of means for packing the valve i against leakage. I

The invention. also contemplates generally improving the construction and enhancing the utility of control valves of this character.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

A. practical structure'for carrying out the invention is illustrated in the accompanying drawings, wherein 2- Figure 1 is a view in elevation of a carburetor equipped with a valve constructed in accordance with the invention;.

Fig. 2 is an elevation of the same viewed from the left of Fig. 1;

Fig. 3 is a plan view of the same;

Fig. 4 is a similar view, parts in section;

Fig. 5 is a detail sectional view taken on the line 55 of Fig. 4.

Referring to the drawings by numerals of reference p The float chamber of a carbureter is inclicated at 1, and this chamber is provided with a cover or top 2 upon which is secured, or with which is integral an intake pipe or mixing chamber 3, which is preferably of Specification of Letters Patent.

Serial No. 268,589.

rectangular cross section as shown. The in take pipe 3 is provided with the usual coupling flange 4 by which it may be attached to the intake manifold of a motor. A block 5 is secured on the top 2 and is formed with an extension or nipple'5, which has a close fit in an aperture formed in one side of the intake pipe 3.

The block 5 is cored or bored to provide inlet ducts 6 and 7 which furnish communication between the iioat chamber and the intake pipe, and the passage through which is controlled by the respective valves 8 and 9.

A strip 10 is placed in the intake pipe 3, and is secured to the wall thereof in any suitable manner, or it may have a close fit in the pipe. A web or division wall 11 is secured to the strip 10 and extends longitudinally of the intake and across the extension or nipple 5; The strip 10 is of sufficient thickness to bring its face flush with the inner end of the nipple 5 so that the division wall 11 will pass easily across the nipple with its edge in close contact with the inner end of the nipple. As will be seen most clearly in Fig. 2, the division wall 11 divides the discharge orifice of the duct 6 from that of the duct 7 Nhile two ducts are herein shown it is to be understood that the device is not limited to any number oi ducts and discharge orifices, as one or a plurality may be used.

An opening 12 is formed in that wall of the intake pipe 3 opposite to the one through which the nipple 5 projects, and into this opening extend the upper or operative ends of valves 13 and 14, of the flap valve variety. These valves 13 and 14 control the admission of air and gas to the intake manifold of the engine, and are mounted on 0pposite sides of the division wall 11 within the intake pipe 3, and the valves are mounted to rock on trunnions 15 and 16, the inner trunnion 16 of one valve resting in a notch formed in the division wall 11 and having a reduced end which fits into a socket formed in the other valve, as seen most clearly in Fig. 5.

Angled arms 18 and 20 are secured to the respective valves 13 and 14 by means of the respective screws 19 and 21, or other suitable securing means. Pins depend from the outer ends of the arms 18 and 20 and are positioned in the respective slots 22 and 23, formed in a cam lever 24, which lever is pivotally secured by a bolt 25, or otherwise,

packing strip 29. Another metallic strip, 30,

is secured to the valves 13 and 14, being clamped in place beneath the arms 18 and 20 and their respective valves. The strips 28 and 30, as will be understood, are divided to permit separate movement with the move ment of the valves.

From the foregoing it will be seen that, when the valves are moved to closed position, the edge of strip 30 will press against the edge of strip 28 and force it against the packing strip 29, thereby closing the space tightly and preventing intake of air therethrough.

A priming valve, such as indicated at 17, may be provided on the carbureter, if desired, though the same forms no part of this invention and will not be described herein.

The operation of the device is as follows Considering Fig. 3, when the cam lever 24 is swung in the direction of the arrow, the lever arm 18 is swung to open the valve 18 while the lever arm 20 remains stationary until its pin has passed from the arcuate portion of the slot 23, which takes place as the pin of arm 18 passes into the arcuate portion of slot 22 and becomes stationary. From this we see that one valve gradually opens to its fullest extent while the'other valve remains stationary, and the second valve begins to open when the first valve is fully opened, and gradually opens to its fullest extent, the first valve remaining stationary during such opening. hen a re verse motion of the cam lever 24 is had, a

reversal of the operation just described takes place, the valves successively closin While the structure has been herein shown as applied to a carbureter provided with the two discharge orifices 6 and 7, it is to be understood that the division wall between these orifices may be removed and one duct connect the orifice thus provided with the I float chamber. 7 By this arrangement the one jet will be acted upon by both valves.

What is claimed is 1. The combination with an intake pipe, of a division wall in the pipe, valves mounted on each side of the division wall, a cam lever, and connections between the cam lever and the valves whereby movement oi the lever operates the valves in succession.

2. The combination with an intake pipe, of a division wall .in the pipe, flap valves mounted on each side of the division wall, and means for successively rocking the valves.

3. The combination with'an intake pipe, of a division wall in the pipe, flap valves mounted on each side of the division wall, angled arms connected to the valves, a cam lever pivoted to the pipe, and connections between the lever and the arms whereby movement of the lever will cause successive movement of the valves.

l. The combination with an intake pipe, of a division wall in the pipe, flap valves mounted on each side of the division "all, an angled arm secured to each flap valve, a pin extending from the outer end of each arm, a pivotally mounted cam lever secured to the pipe, said lever having cam slots for the reception of the pins, and means for packing the valves.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

XVILLIAM A. HEIDE.
